Rather than use a combination of id lookups on the groups table and a group configuration cache in the scheduler, I've moved the groups and group config into json objects on the deck table. This results in a net saving of code and saves one or more DB lookups on each card answer, in exchange for a small increase in deck load/save work. I did a quick survey of AnkiWeb, and the vast majority of decks use less than 100 tags, and it's safe to assume groups will follow a similar pattern. All groups and group configs except the default one will use integer timestamps now, to simplify merging when syncing and importing. defaultGroup() has been removed in favour of keeping the models up to date (not yet done).
